root int anaInEERd(unsigned int channel, unsigned int opmode, unsigned int gaincode);

Reads the calibration constants, gain, and offset for an input based on their designated position in the flash memory, and places them into global tables _adcCalibS, _adcCalibD, and _adcCalibM for analog inputs. Depending on the flash size, the following macros can be used to identify the starting address for these locations.

ADC_CALIB_ADDRS, address start of single-ended analog input channels ADC_CALIB_ADDRD, address start of differential analog input channels ADC_CALIB_ADDRM, address start of milliamp analog input channels

NOTE: This function cannot be run in RAM.

PARAMETER

channel is the analog input channel number (0 to 7) corresponding to LN0_IN to LN7_IN. opmode is the mode of operation:

SINGLE—single-ended input line DIFF—differential input line mAMP—milliamp input line

channel	SINGLE	DIFF	mAMP

0	+AIN0	+AIN0 -AIN1	+AIN0*
1	+AIN1	+AIN1 -AIN0*	+AIN1*

2	+AIN2	+AIN2 -AIN3	+AIN2*

6	+AIN6	+AIN6 -AIN7*	+AIN6

7	+AIN7	+AIN7 -AIN6*	+AIN7*

ALLCHAN	read all channels for selected opmode
